I overlayed a 7D and lined up the mounting ring as best I could (first pic), then traced around the sensor on the 7d and overlayed that on the EOS-M (second pic).

Pretty sure that's aps-c we're looking at.

What also intrigues me is that it looks like the diameter of the lens mount is large enough to accomodate a full frame sensor. It looks like Canon may be playing the long game here, with a view to a strategic investment in a system which can be extended, rather than looking for a quick win.

Of course it's large enough, it's an EF series mount. But you're right, Canon (as usual) are playing the big picture long game here. They would never put everything on the plate straight away, got to leave enough features out to enable yearly upgrades.

It certainly won't be called "M", since it's a more direct competitor to Leica's system than the Olympus OM was back in the 70s, and Leica gave them huge grief over their original name of "Olympus M". If the Japanese text says the name "M" is part of the rumor, this alone tends to discredit it.

The front element looks way too small for a retro-focus 22mm lens. The length of the lens is thicker than the body. assuming the body is about 22mm ( body thickness of NEX). Therefore the 22mm must be a retro-focus lens. Also if the body thickness is 22mm, then the lens mount looks like is about 80mm. That is a lot bigger than the EF mount (65 mm). Also the lens says EF_M. This term is created by one of our poster. Does he really have a ESP??? I think some one created the picture. I do not believe it is the real thing.The name Mr. Pink sound too close to MR. Plank

Err.. the outer diameter (filter size) is only 43mm. It says so. Nowhere near 80mm This is a lot smaller than an EF lens.

Also, it was confirmed that the 1DX will be able to focus at f8 with a firmware update, however the rep couldn't confirm ths for the 5D.

Now that is a very interesting piece of news, if it turns out to be true (not doubting you, just not sure about the rep you spoke with, and how much they really know vs. make up on the spot...).

The rep knew the answer to the question on the spot, they definitely didn't hesitate with the answer. I haven't named the rep or their position as I didn't/don't want to incriminate, but suffice to say it wasn't just a salesperson, it was someone pretty high up in Canon NZ professional camera division.

Did I also mention I played with the 1DX (also very very nice!), and the C300 (what a strange beast that thing is, doesn't feel like $20,000 to hold!)

Also saw some of the new IS primes, but not much to say about them, they're pretty boring hehe.

Could you tell us something about the new 24-70 lens? I'm interested in that as well

The new 24-70 felt quite a bit lighter and less bulky than the current one. It's not as long when fully zoomed out (extended). Unfortunately they've changed the hood so it now attaches to the barrel part that moves, rather than remaining on the main part of the lens and having the barrel move inside it.
